TYPES AND STRUCTURAL CONTROL OF GOLD DEPOSITS IN THE TONGGUANSHAN ORE FIELD,ANHUI PROVINCE
-
摘要: 铜官山矿田是我国著名的铜矿田和铜产地之一,近年来又相继发现了一批金矿床,属于与铜矿床具有成因联系的共生金矿床,主要有铁帽型和硫化物型。本文主要阐述金矿床的类型、地质特征及构造控矿作用。认为该区硫铁矿亚型和铁帽亚型金矿床均属于与燕山期中性-中酸性侵入岩具有成因联系的岩浆热液型矿床,只是氧化、剥蚀与保存条件不同而以不同类型出露。金矿体的产状严格受铜官山倒转背斜不同部位地层岩石的产状及其层间断裂的控制。Abstract: Tongguanshan is a famous copper ore field and one of copper-producing areas of China. Recently a number of gold deposits have been found, which belong to the sulfide type and gossan type and are genetically related to copper deposits in the ore field. The paper mainly deals with the types, geological characteristics and structural controls of gold deposits, The author considers that both the two types of gold deposit belong to the magmatic hydrothermal type genetically related to Yanshanian intermediate and intermediate-acid intrusive rocks, and its outcropping as different types of ore deposit is just due to the differences in oxidation-denudation and preservation conditions. The attitude of gold ore bodies are strictly controlled by that of the strata in different parts of the Tongguanshan overturned anticline and interlayer faults.
